安卓编译java变量错误

Question

我正在尝试通过一个小的添加来构建安卓，但我给了我以下错误：

packages/apps/Settings/src/com/安卓/settings/cyanogenmod/ProgressBar.java:144: cannot find symbol symbol : variable ram_bar_button_reset location: class com.安卓.settings.R.string menu.add(0, MENU_RESET, 0, R.string.ram_bar_button_reset) ^ packages/apps/Settings/src/com/安卓/settings/cyanogenmod/ProgressBar.java:162: cannot find symbol symbol : variable ram_bar_reset location: class com.安卓.settings.R.string alertDialog.setTitle(R.string.ram_bar_reset);

当我打开带有相应行的文件时：

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{       
menu.add(0, MENU_RESET, 0,
R.string.ram_bar_button_reset)
    .setIcon(R.drawable.ic_settings_backup)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);   
}

以及：

private void resetToDefault() 
{       
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(getActivity());
    alertDialog.setTitle(R.string.ram_bar_reset);
    alertDialog.setMessage(R.string.progressbar_reset_message);
    alertDialog.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() 
{           
public void onClick(DialogInterface dialog, int id) 
{
    ProgressBarColorReset();            
}       
});         

    alertDialog.setNegativeButton(R.string.cancel, null);
    alertDialog.create().show();    
}

谁能告诉我该怎么办

从字符串中获取字符串值。xml，您应该使用：Reference

String myStr = getResources().getString(R.string.myStringID);

在你的情况下，试试看

getResources().getString(R.string.ram_bar_reset);

alertDialog.setTitle( getResources().getString(R.string.ram_bar_reset));
alertDialog.setMessage( getResources().getString(R.string.progressbar_reset_message));
alertDialog.setPositiveButton(getResources().getString(R.string.ok), new DialogInterface.OnClickListener() ;

确保res\values\strings.xml包含名称定义如下的字符串：

<resources>
    <string name="ram_bar_reset">Reset RAM Bar</string>
    <string name="progressbar_reset_message">Reset Progress Bar</string>
    <string name="ok">OK</string>
</resources>

编辑：根据要求进行最终Java：

代码块1:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{       
menu.add(0, MENU_RESET, 0,
getResources().getString(R.string.ram_bar_button_reset))  // <   Changed Here
    .setIcon(getResources().getDrawable(R.drawable.ic_settings_backup))  // <  Changed Here
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);   
}

代码块2:

private void resetToDefault() 
{       
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(getActivity());
    alertDialog.setTitle( getResources().getString(R.string.ram_bar_reset)); // <   Changed Here
    alertDialog.setMessage( getResources().getString(R.string.progressbar_reset_message)); // <   Changed Here
    alertDialog.setPositiveButton(getResources().getString(R.string.ok), // <   Changed Here
                new DialogInterface.OnClickListener() 


    {           
    public void onClick(DialogInterface dialog, int id) 
    {
        ProgressBarColorReset();            
    }       
    });



    alertDialog.setNegativeButton(getResources().getString(R.string.cancel),// <   Changed Here
                                     null);
    alertDialog.create().show();    
}
